"Advanced Portfolio" realized gain/loss

[John E. Sterbenz, Jr.]

Is there anything other than a unit sale that would trigger an 
increase/decrease in "realized gain" as found in the Advanced Portfolio 
report?

I am tracking several securities in GNUCash and have never sold any of 
the shares purchased.  There are no brokerage fees, and there's been 
nothing like splits, reverse splits, etc. for any of them.  Some pay 
dividends (which are reinvested), some don't (shouldn't matter).  
However, nearly all of them report a realized loss (in addition to the 
unrealized loss, which is also reported).

I'm running GNUCash version 2.4.7 (built from svn r20813 on July 2, 
2011) on a 64-bit version of Win7.  I've been using this version for 
some time, but only recently took the time to add 16 year's worth of 
end-of-month close pricing data (not knowing that the price calculated 
when adding transactions didn't end up in the Price Editor as it did in 
MS Money).  It was analyzing the results of this work on a 
month-by-month basis via Advanced Portfolio that I identified this.  Any 
ideas?

Thanks for any insight anyone might have!
